man EXTINGUISHER. y

Application filed May 12,

This invention relates, to a fire extinguisher, the general object of the invention being to makeA the extinguisher somewhat in' the form vof a'pistol so thatv it c an. be easily handled to direct the extinguishing liquid against the flames, the controlling valve` being operated by a trigger which .is manipulated by the same hand which grasps the handle. Another object of the invention is to provide the device with vsiphons vfor leadingthe liquid from the reservoir to the discharge i e. v

A further object of the invention is to provide means for introducing compressed air into a chamberV in the device which, when the valve is opened, will act on the liquid to force the samefrom the device, the coinpressed air being introduced .into the device by means of an air pump or the like.

This invention also .consists 1n certain yother features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illus- .trated in the accompanying drawings and specifically pointed. out` in the. appended claims. In describing my invention in detail, refferenc'e will be had to the accompanying drawings wherein like characters denote-- several views, and 'in which:-

Figure lisa longitudinal sectional view through the device.

Figure 2 is a section on line 2-2 of Figure 1.

Figure 3 is a view of the rear end of the device.

Figure 4 is a section on line 4--4 of Fig- 40 ure l. y

' Figure 5 is a lsectional view through the valve of the device. 'A

In thesevi'ews, 1 indicates the casing which forms the body of the device, this casing being preferably of cylindrical shape with a pointed front end and an open. rear ,end, this rear end being closed by a screw cap 2. A pistol-like handle 3 is formed on the c'asing and depends from the. under side thereof.

like or corresponding parts throughout the Partitions 3 divide the casing into a liquidy chamber or reservoir 4, a front air chamber 5, a rear air chamber 6 and a gauge chamber f7. A tube 8'eonnects the two air chambers together, said tube passing through the reservoir 4. A filling opening, closed by a plug 9, is arranged in the top of the casing forl 192e sevriai Np. 108,656..

permitting liquid to be placed in the chamber 4, and an air valve 10 is arranged on the top of the casing and communicates with the frontair 'chamber 5 so that air can be forced into the air chambers. This valve is made to fit an ordinary air supply system or pump.

A rear Siphon tube lllleads from the rear part of" the liquid reservoir to the lower part of the handle and a front siphon tube 12 leads from the front part of the reservoir 4 into the lower partof the handle, these tubes having their horizontal lparts resting I v upon the bottom of the` reservoir. `A discharge tube 13 extends from the bottom of the handle through the reservoir and the front air chamber, with its outer end extending into the nozzle 14.l Tubes 15 connect the air chamber 6 with the top of the reservoir 4, one of these tubes being arranged exterior of the casing' and'having a valve seat 16 therein which is engaged'by a spring pressed -valve 17, the stem of which passes through a tube 18 in the upper part of the handle and is connectedwith the trigger 19 pivoted to the lower part of the casingiad- `jacent the handle. `When this trigger is pressed upon, the valve 17 will be forced off its seat so that air can flow from the air chambers into the top of the reservoir, thus placing the liquid in the reservoir under pressure. This liquid Will- How through the I Siphon tubes and be discharged through the Atube `13 with great force. 'By having two Siphon tubes, the liquid will pass through the tube 11 when the device 'is pointed upwardly and' through the tube 12 when the .device is pointed downwardly.

A hand operated valve 20 is arranged in' one of the tubes 15 to close the communication from the air chambers to the liquid reservoir to-prevent leakage of air. The cap 2 is provided with an arc-shaped window 21 so that the linger 22 olf-'the 'air guage 23 .can be observed. This cap also carries a scale 24 for the finger.

Thus it will be seen that I have provided a simple form of lire extinguisher which is mainly designed for us-e in automobiles. and the like, which works like a pistol. When a fire occursthe valve 2O isopened and the handle 3 grasped by the hand, with one finger on the trigger 19. `The device is then pointed at the flames and the trigger pressed i upon to open the valve 17 so that air will pass from the air chambers into the liquid reservoir. Thus the liquid Will rbe forced from the reservoir, through the discharge tube 13v and it will pass from' the nozzle 151 With considerable force. The siphondtube 1l lwill insure emptyingl of the reservoir when the dwice is pointed upwardly and the siphon tube -12' will insure emptying of the reservoir' whenthe device is pointed downward-ly.

' It is thought from the foregoing description that the advantages and novel features of my invention will be readily apparent. I desire it to be understood that I may make changes in the construction and in the combination and arrangement ofthe several' parts, provided that such changes fall Within thehscope of the appended claims.

l. Are extinguisher comprising'a cylindrical casing having front and rear end Walls, a pair of partitions. in the casing dividingvthe'same into a central reservoir and end air chambers, a hollow handle depending from and' in communication VWith said central reservoir, a tube passing through the partitions for connecting the tivo end chambers together, normally closed liquid inlet ineans opening into said reservoir, nornrally closed air inlet means opening into one of. said air chambers serially joined, tubes connecting therear air chamber to the top of the reservoir, some of the tubes being arranged exterioily of the casing and under the same, a valve in one of the exterior tubes. a trigger. pivoted to the casing and arranged lrior of the handle.

2. A fire extinguisher comprising a closed .adjacent the handleymeans for `connecting 35 Where it is in communication with the inte- 40 casing having a nozzle at its front-end, pai'- titions inthe casing dividing the saine into a reservoir Aand an air chamber, a hollow handle depending from the centraly part fof said reservoir and spaced a substantialdistancefrom each end thereof, said handle being in communication with said reservoir,

normally closed liquid inlet means opening arranged exterior of the'casing, valve means 55 in the exterior pipe, a trigger pivoted to the bottom of the casing adjacent the handle, a valve stem connected with the Valve means and pivoted to the trigger, a discharge pipe in communication with the reservoir and having its-outer end engaging the nozzle, said discharge pipe extending into the bottom of the handle and front and rear Siphon tubes having portions in the bottom of the reservoir and otherportions extendingI to' 65 the bottom ot' the handle.V

In testimony whereof I` affix my signature. ALBERT STRAUBHAAR.
